A new species of Eranthis (Ranunculaceae), E. pungdoensis B.U. Oh is described from Pung-do, Ansan-si, Gyeonggi-do in Korea. The new species is distinct from E. byunsanensis, its closely relative species, in having broad funnelform petals, 2.5-3.7 mm long, 2.4-3.5 mm wide and restricted distributional area.

This study was carried out to find specific characters of the seed morphology and anatomy of Korean Eranthis in Ranunculaceae. As a result, E. byunsanensis differs with E. stellata on the basis of presence of unicellular hairs on the seed surface. E. stellata has no unicellular hairs on its seed surface. On the other hand, E. byunsanensis bears such unicellular hairs derived from epidermal cells of the seed surface. Besides other morphological characters used when it was published as a new species, the presence of unicellular hairs on the seed surface strongly supports it as an endemic species of Korea. In addition, to compare the seed morphology of E. pinnatifida and E. pungdoensis, for which mature seeds were not available at this time, an additional study should be conducted in near future.

Fruit and seed morphological characteristics were investigated in 36 taxa of 20 genera of Korean Ranunculaceae. As a result, fruits were classified as the achene, berry, or follicle type. In the taxa with achene, the presence of trichomes and stoma on the surface of the fruit and a feature in which the endocarp distinctively develops into a one-layer sclereid were considered as useful characteristics. Moreover, in the taxa with follicles, the composition of the seed coat (bitegmic vs. unitegmic), the cell shape of the seed coat, the presence of trichomes, and the type of seed coat were useful for taxonomic characteristics in Korean Ranunculaceae. Based on the fruit and seed characteristics, Adonis is likely to be classified into Helleboroideae rather than Ranunculoideae, as it has bitegmic ovules. In addition, Enemion is similar to Eranthis in unitegmic ovule and the seed coat structure which has non-sclereid exotesta; therefore, it is reasonable to be placed in Helleboroideae. According to the results of this study, more in-depth research is needed regarding the taxonomic positions of Callianthemum and Actaea, which has the only berry fruit type.
